This invention relates to new and useful'improvements in a transporting device.

' This application is a substitute for my abandoned application filed on March 14, 1947, Serial The invention proposes a. transporting device which may be conveniently used to support and carry crates, boxes, luggage and which may be combined in a novel manner to facilitatemovement of a-motor vehicle having a flat tire.

More specifically, the invention proposes to characterize the transporting device by a pair of end support members longitudinally spaced from each other and connected in a certain way and provided with gripping elements for engaging the load, and also provided with casters by which the load may be supported upon the ground or floor and rolled or pushed along.

The invention proposes that one or more of the carriers be combined to receive and support the fiat tire of a motor vehicle permitting movement of the car to a service station.

"Still further it is proposed to further characterize the transporting device by a pair of pivotally connected strips adjustably connected with the support members which are provided with the casters so that the transporting device may be folded when not in use. v

' Still further the invention proposes an embodiment of the transporting device to adapt it to support a wheel or wheels of an automobile so that the automobile may be towed or pushed when this is required.

For further comprehension of the invention, and of the' objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth. v

. In the accompanying drawings forming a material part of this disclosure:

The transporting device, in accordance with this'invention, includes a pair of and support members 1 l0 and II-- normally longitudinally spaced from each other and provided with gripping elements I! and 13 for engaging a load. Wheels M are mounted on the bottom of-said support members I!) and II. A pair of pivotally connected strips [5 and I6 are adjustably connected with the said end support members 10 and 'II,

. The strips l5 and [6 are pivotally connected with each other by a pintle pin l1 and coil portions 18 formed on the adjacent ends of the strips and engaged around the pintle pin H. The strips l5 and I6 are adjustably connected with theend support members l0 and II- by-1.1ugs. l9 formed on the edge portions of one ofthese-parts and engaging the edges of the otherof, th'eparts. Fastening elements 20, such ascrews, are mounted on one of the parts and engage through slots 2| formed on the otherpf the p t in .'nutS 22 engage the screws and normally abut the edges of the slots 2|. I hese wing nutsserve to on the end support members I0 and H.

The gripping elements 12 comprise a pair of spaced lugs upon the outer ends of thesupport members I0 and ll. The gripping elements-J3 compriselugs upon one of the, sides of the said end support members In and I! near thepll ier ends thereof.

The operation of the transporting device may be best understood by examining Fig. 1 and noting the device is shown engaged beneath the bottom corner of a crate 25. It is pointed out that the transporting device may be adjusted in width to accommodate the width of the crate 25. While one device has been illustrated it should be clearly understood that an additional one may be used upon the remote end of the crate 25. When the transporting device is not in use it may be folded clamp the strips l5 and I6 inadjusted positions to 7, are used. These devices are disposed par- 7 allel to each other and slightly laterally spaced and joined together with an arcuate-memher'n'iir This arcuate member is provided with a. pair of spaced lugs Zl provided withffastening screw 28 normally engaged through openings 7.9 in the;

gripping elements l3 of the load carrier units. The arcuate member 26 is also provided with several straps 30 adapted toengage around the tire andirimiof. the; wheel 25.- The arcuate; member 7 26 is of a shape to=contormzwith the bottom' POP.- tionofthe wheel asshown Figs. 8 and 9, or; it is flexible so that it may be forced. to consfiorm:
